Title: A method for treating capsules used for drug storage
Inventor: CLARK ANDREW R
IPC: A61K9/00
Filed: 1995-06-29
Abstract: Capsules (such as hard gelatin, cellulose and plastic capsules) containing pharmaceutical powders which are administered to a patient via inhalation are treated so as to increase the effective amount of the pharmaceutical agent reaching the respiratory system of the patient. The capsules are coated internally with a lubricant during manufacture and in one aspect, the method involves exposing the lubricant-coated inner surface of the capsule to a pharmaceutically acceptable solvent which dissolves the lubricant. Generally, the solvent is volatile, and bactericidal (e.g. ethanol). The pharmaceutical powder is inserted in the capsule following this washing procedure. Alternatively, the lubricant-coated capsule is dusted internally with a dusting agent such as a salt (e.g. sodium chloride) or a sugar (e.g. lactose, mannitol, trehalose or sucrose) prior to inserting the pharmaceutical powder inside the capsule. The invention also pertains to a capsule, optionally containing the pharmaceutical powder therein, which has been treated according to the methods discussed above.

Title: Electrical interconnect contact system
Inventor: RATHBURN JAMES J
IPC: H05K7/10
Filed: 1997-06-23
Abstract: An electrical connector that uses an elastomeric element to provide a short path, high performance, electrical interconnection that is mechanically stable and reliable. In accordance with the present invention, lateral movement of the contacts is controlled by providing contact receiving slots formed in a rigid housing and/or an alignment plate. Movement of the contacts during actuation is controlled, at least in part, by specifying the compression properties of an elastomeric element, providing a contact stop portion in the housing, and/or providing a pre-load between the contacts and the corresponding printed circuit board terminals. Because the movement of the contacts is controlled, the wiping action between the contacts and the device leads and/or the printed circuit board pads is also controlled, resulting in a more reliable contacting system.
